Mysql-如果只有时间戳，如何按年份选择行？

Question

我有这张桌子

Id      Timestamp
1    |  1302566399
2    |  1502745635
3    |  1374679999
4    |  1264575886
5    |  1154645755

如何仅选择年份为2011的行？

Answer 1

SELECT * FROM table WHERE FROM_UNIXTIME(timestamp, '%Y') = 2011;

Answer 2

已经在其余答案中建议了最简单的方法（直接来自查询）

你也可以这样

$year_start = strtotime('2011-01-01');
$year_end = strtotime('2011-12-31 23:59:59.000');

$sql = "SELECT * FROM your_table 
        WHERE Timestamp>=$year_start AND Timestamp<=$year_end";
$res = mysql_query($sql);

函数strtotime（）取决于时区设置。

Answer 3

SELECT * FROM t WHERE YEAR(`timestamp`) = 2011

Answer 4

select * from table where from_unixtime(field,'%Y') = 2011

Answer 5

尝试这样的查询，其中myTimestamp是其中带有时间戳的列

SELECT * FROM myTable WHERE FROM_UNIXTIME(myTimestamp, '%Y') = '2011'
